To all whom it may concern:

Be it known that we, OERiN R. CLARK and FRELON H.

D D represent the jaws, riveted to leather strap C, which is riveted to the handle AA at a. The eccentric E, when raised to the position as represented by the red lines E', allows the jaws D D to open, as represented by the red lines D.

To operate the machine, place the upperleather of the boot to be lasted between the jaws D D and bring down the eccentric E to force the jaws D D to hold tight to the upperleather, and place the round end B of lever A A on the opposite side of the boot and press upon the handle A A at H, which Will draw the upper-leather over the insolesrnoothly to its place. A

Fig. 2 is a top view of the shank-laster.

We also intend to have a steel spring placed between the jaws D D, to throw them open when the pressure is removed.

What we claim as our invention, and desire to secure by Letters Patent, is-

fllhe handle or lever A A, strap C, jaws D D, and eccentric E, in combination, arranged and operated in the manner and for the purpose set forth.
